Subject: [xsl] Parameters into variables

Hello,

XSLT 1.0 (e.g. Firefox 3.0, etc.)

I have a template as follows:

<xsl:template name="getCurrencySymbol">
<xsl:param name="aCurrency" />
<xsl:choose>
<xsl:when test="$aCurrency='AUD'">A$</xsl:when>
<xsl:when test="$aCurrency='EUR'">&#x20AC;</xsl:when>
<xsl:when test="$aCurrency='GBP'">&#163;</xsl:when>
<xsl:when test="$aCurrency='NZD'">NZ$</xsl:when>
<xsl:when test="$aCurrency='USD'">US$</xsl:when>
<xsl:otherwise></xsl:otherwise>
</xsl:choose>
</xsl:template>

At the top of my xsl stylesheet I want to put its value into a global variable:

<xsl:variable name="theCurrencySymbol">
<xsl:call-template name="getCurrencySymbol">
<with-param name="aCurrency" select="'NZD'" />
</xsl:call-template>
</xsl:variable>

But this does not work. Mangano (2003, p.120) shows that it will work if the template is called _without_ a parameter, and indeed I am able to do so successfully if I use a global variable, e.g. $baseCurrency, and change my getCurrencySymbol template so that it uses $baseCurrency (i.e. ignoring the $aCurrency parameter).

The problem is that I would like to be able to re-use my getCurrencySymbol template elsewhere, but with a specified parameter in its call rather than a global.

Is it really not possible to put the result of a template into a variable, if that template is being called using a parameter? I cannot think why such a minor distinction would be in the language.

Cheers!

Joe

<with-param name="aCurrency" select="'NZD'" /> should be <xsl:with-param name="aCurrency" select="'NZD'" />

or was that just a copy-paste error?
